Description

Technical Field

[0001] The present invention relates to the technical field related to urological surgical equipment, in particular to a urinary catheter for urological surgical use. Background Art

[0002] The catheter used in urology, also known as a urinary catheter or a catheterization device, is a slender and soft tube, usually made of medical-grade plastic or silicone with good biocompatibility and flexibility.

[0003] Publication number CN213432036U discloses a urinary catheter for urology, which belongs to the field of medical equipment. The urinary catheter includes a catheterization part, a drainage part, a urination part and an airflow part. When the device is used for catheterization, the insertion end of the urinary catheter lubricated by the lubricant in the movable tube can be inserted into the patient's urethra by sliding the movable tube, thereby facilitating insertion; and because the lubricant is not temporarily applied manually, secondary contamination can be effectively reduced; in addition, the application also provides an air pressure pump, which slowly draws out the urine in the patient's urethra by extracting air pressure through the air pressure pump, which can reduce the patient's discomfort during use, and can also make the urine in the patient's urethra all drained into the drainage part, overcome the residual urine in the patient's perineum, and further improve the patient's use experience; further, by providing a urination part, when the capacity of the urination part to receive urine is certain, it can be processed in time to further avoid the occurrence of odor.

[0004] The urological catheter in the above patent is complicated to operate and needs to be installed and catheterized by medical staff. Urine leakage may occur at the connection between the catheter and the urethra, which can easily contaminate the catheter and the ground. Manual cleaning is required after catheterization, which is very inconvenient. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the present invention provides a urinary catheter for urology to solve the problems existing in the above background technology.

[0006] The present invention provides the following technical scheme: a urinary catheter for urology, comprising a guiding device and a liquid level warning device, the guiding device comprising a first shell, the first shell having a No. 1 hole, a second shell being arranged inside the first shell, the second shell having a No. 2 hole, a connecting block being fixedly connected to the inner wall of the second shell, a third shell being arranged inside the second shell, a rectangular groove being arranged on the third shell, a connecting pipe being threadedly connected to the bottom of the third shell, a filter groove being arranged inside the connecting pipe, a chuck being movably connected to the inner wall of the connecting pipe, a connecting rod being fixedly connected to the top of the chuck, a limiting disk being fixedly connected to the top of the connecting rod, the second shell being sleeved inside the first shell, the third shell being sleeved inside the second shell and the connecting block being stuck in the rectangular groove arranged on the third shell when being sleeved, a drainage tube being fixedly connected to the bottom of the connecting tube, the drainage tube The upper movably connected device is provided with a fixing device, and the fixing device includes an auxiliary plate, and a fixing block is fixedly connected to the side of the auxiliary plate, and a connecting column, a front gasket and a rear gasket are fixedly connected at the center of the auxiliary plate, and a fixed elastic rope is fixedly connected inside the fixing block. During use, the position of the first shell and the second shell can be adjusted during assembly, and then the opening size of the connection between the No. 1 hole and the No. 2 hole can be adjusted. When the third shell and the connecting pipe are sequentially connected to the second shell, urine enters the second shell through the first shell, and then enters the third shell, and then is discharged into the drainage tube through the connecting pipe. When urine backflow occurs, the backflowing urine will lift the chuck upwards, so that the chuck is blocked at the connection between the connecting pipe and the third shell to prevent urine backflow. After the guiding device is installed, the urethra opening is blocked by the front gasket and the rear gasket by pushing the fixing device upwards to prevent urine from flowing out from the outside of the drainage tube.

[0007] When in use, first determine the insertion depth and push the fixing device to the corresponding position, then insert the guiding device into the urethra. After being inserted to the specified depth, the auxiliary plate is located at the male reproductive organ. Then the auxiliary plate is pushed upward so that the rear gasket enters the urethra and the front gasket is outside the urethra. The rear gasket and the front gasket will expand after absorbing water to block the urethral opening. At the same time, the fixing elastic rope is unfolded and put on the front end of the genitals to complete the fixation of the device. It is not easy to fall off during use and can also prevent urine from leaking from the gap between the device and the urethra. The operation is simple.

[0008] Furthermore, a urine collecting bag is fixedly connected to the bottom of the drainage tube, a connecting belt is fixedly connected to the side of the urine collecting bag, a lock buckle is fixedly connected to the connecting belt, and a connecting device is fixedly connected to the side of the urine collecting bag.

[0009] Furthermore, an active switch is fixedly connected to the drainage tube, and a guide tube is movably connected to the other end of the active switch, and a guide air bag is fixedly connected to the other end of the guide tube. When urinating, the active switch is closed, and the air inside the guide air bag is discharged by pressing the guide air bag. Then, the active switch is turned on to connect the guide air bag and the drainage tube. The guide air bag draws air from inside the device to assist urination, which is beneficial to guiding urine from the guide device into the drainage tube.

[0010] Furthermore, the liquid level warning device includes a device shell, a fixed plate is fixedly connected to the bottom of the device shell, a sleeve rod is fixedly connected to the center of the fixed plate, a movable rod is movably connected to the center of the sleeve rod, a connecting head is fixedly connected to the bottom of the movable rod, and floating plates are rotatably connected to the two side surfaces of the connecting head, and a pressure sensor and a buzzer are fixedly connected to the inside of the device shell, and the buzzer and the pressure sensor are electrically connected. When in use, the float plate is pushed upward by the liquid inside the urine bag, driving the movable rod to move upward. If the liquid inside the urine bag reaches the set value, the movable rod will move around and squeeze the pressure sensor upward. After receiving the pressure, the pressure sensor activates the buzzer, thereby reminding the patient that the urine bag is full and the bag needs to be changed.

[0011] Furthermore, the first shell and the second shell are made of silicone material, which has good flexibility and durability, can reduce pressure and irritation to the urethra, has good comfort and is not easy to be blocked. The third shell, the connecting tube and the drainage tube are made of polyurethane material. Polyurethane is harder and can better maintain the shape of the external first shell and the second shell after entering the urethra, play a supporting role, and avoid deformation after entering the urethra, thereby affecting the catheterization effect. The surface of the first shell and the second shell is coated with a coating with antibacterial function. The coating is a silver ion coating or a hydrogel coating, which can form a barrier to prevent bacteria from attaching and multiplying on the surface of the catheter, helping to reduce the accumulation of bacteria on the catheter, thereby reducing the risk of urinary tract infection.

[0012] Furthermore, the liquid level warning device is arranged at the connecting device on the urine receiving bag and is connected to the urine receiving bag through threads. The floating plate and the movable rod are made of lightweight plastic and are more susceptible to buoyancy.

[0013] Furthermore, the auxiliary plate on the fixing device is made of transparent ceramic, the front gasket and the rear gasket are made of water-absorbing resin, and the fixing block is made of silicone.

[0014] Furthermore, a scale is provided on the drainage tube between the guiding device and the movable switch, which facilitates observation of the insertion depth of the guiding device during use.

[0015] Beneficial effects:

[0016] 1. The urinary catheter for urology is provided with a guiding device and a fixing device. When in use, the guiding device is used to guide urination, and the fixing device is used to fix the drainage tube, thereby avoiding urinary tract infection caused by urine reflux. The operation is simple during use, and the patient can also install it by himself, which is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
